Abstract

We are developing an X-ray mirror using the carbon fiber reinforced plastic (CFRP) as a substrate in order to improve the angular resolution of tightly-nested thin-foil Wolter-I X-ray mirrors. We found that curing of the epoxy used in the replication process at the room temperature is effective to suppress the print through. We were able to make mirrors whose shape accuracy is 3 - 5 μm. Characterization at the synchrotron facility SPring-8 using the X-ray pencil beam of 20 keV showed that the angular resolution was 3 - 5 arcmin as a whole, but can reach to 20 arcsec locally.
